Working hypothesis and aims: The use of TCM will improve the status of children with chronic ITP and thus will reduce the need to use conventional medications. The investigators aim to study whether in children with chronic ITP, supplementation with TCM, improves the bleeding symptoms and ITP-related quality of life (QOL) compared to the period prior to the intervention? Methods: The study includes three periods: 1st observation period (1 month), TMC period (3 months) and 2nd observation period (2 months). During all study periods the following data will be collected: bleeding symptoms, bleeding score, platelet count, need for conventional therapy, side effects of therapy and ITP-related QOL.
